Mark Forest is correct, you would make the current owner responsible for delivering the property to you vacant and empty of any chattels or property not explicitly itemised as being delivered with the property in the APS.We use attorneys for closing up here, but you would need either an attorney, title company or both to execute this on your own.It has also been our experience that FSBOs are usually over priced - sometimes those from other investors are close to reality, but not always.
